Hi

I'm working through the introductory DBI documentation and thought I'd try out a bit of code

         foreach (@{ $DBI::EXPORT_TAGS{sql_types} }) {
           printf "%s=%d\n", $_, &{"DBI::$_"};
         }

but it doesn't seem to work. It seems to pull up the sql_types tags but this code 

#!/usr/bin/perl

use strict;
use warnings;
use CGI;
use DBI;
use DBD::mysql;

print "Content-Type: text/html\n\n";

foreach (@{ $DBI::EXPORT_TAGS{sql_types} }) {
  printf "%s=%d\n", $_, &{"DBI::$_"};
}

[download]

results in the error message 

Content-Type: text/html

Can't use string ("DBI::SQL_GUID") as a subroutine ref while "strict r
+efs" in use at ./tmp.cgi line 12.

I can fix this by not using use strict; but I'd rather not. I have a Super Search on while "strict refs" in use to understand more about this error in general. However I usually fix/rewrite the code when I get this error. I'm just a bit stumped on how to get to the subroutine that returns the value of the sql_type

Is there a better way to achieve what this code sets out to do with use strict; in play?
